For reference, a "fieldhouse" doesn't exclusively mean a large indoor field. The Collicutt Centre in Red Deer has the amenities that make up the traditional fieldhouse, just at a smaller scale.
Another good example of a fieldhouse in Canada is that of Carleton University in Ottawa. Spoiler for size:
Also the Manulife Sportsplex in Kitchener-Waterloo:
